Abstract (en)

[origin: EP3281742A1] A polishing method comprises: conveying a workpiece by using a transmission mechanism with a to-be-processed surface of the workpiece facing down; and polishing the to-be-processed surface under the to-be-processed surface by using a polishing device. During polishing of a workpiece according to the polishing method, a to-be-processed surface of the workpiece is faced down, and the to-be-processed surface is polished under the to-be-processed surface of the workpiece by using the polishing device, so that abrasive dust generated during polishing can fall down due to self-weight. Therefore, the polishing method can effectively prevent abrasive dust from remaining on the to-be-processed surface of the workpiece, thereby increasing the polishing efficiency and improving the polishing effect.
